This invention relates to improvements in buckets and, more especially,an excavator bucket or shovel.

My invention is especially applicable in connection with the form ortype of bucket now generally known as the Page bucket used in variouskinds of excavating machines, such bucket usually being filled or loadedby dragging or drawing the same in a more or less horizontal or inclinedposition through the material to be dug. The bucket, after being filledor loaded, is ordinarily lifted by chains or cables supporting thebucket by trunnions on the side and then moved to dumping positionwhereupon the loading line is released, allowing the bucket to tilt onthe trunnions and dump its contents.

Buckets of the character referred to are subjected to hard and roughusage and frequently dropped onto the ground with more or less impact.

Among the features of my invention is the construction of such a bucketthat gives great rigidity, strength and durability with a minlmum costand weight.

My bucket is also so constructed that portions thereof subjected to thegreatest amount of wear or deterioration can be rather easily replaced.

Another feature of my invention is the construction of such a bucketemploying cast portions in combination with suitable plates.

Other features and advantages of my invention will appear more fully asI proceed with my specification.

In that form of device embodying the fea tures of my invention shown inthe accompanying drawings- Figure 1 is a view in side elevation; Fig. 2is a view taken as indicated by the line 2 of Fig. 1; Fig. 3 is afragmentary view of the bottom rear end of the bucket; and Fig. 4 is aview taken as indicated by the line 4 of Fig. 1.

As shown in the drawings, the entire bot- 1931. Serial No. 533,290.

tom of the bucket is formed of a single casting, indicated in general by10. This casting includes a fiat bottom portion 11 with side walls 12and a curved rear wall 13..

The forward edge of the bottom portion 11 may be provided with anysuitable digging teeth 14, forming no part of the present invention. Y

The upper edges of the sidewalls 12 are bifurcated or divided to formupwardly eX- tending separate vertical flanges, the inner of these beingindicated by 15, and the outer, by 16. The upper edge of the curved rearwall 13 is likewise similarly divided to form an outer flange 16a and aninner flange 15a. It is to be understood that the flanges 16 on thesides merge with the flange 16a at the rear of the bucket, to formcurved corners, and likewise the inner side flanges 15 merge with therear flange 15a.

The sides and rear of the bucket (the front of the bucket is open) areformed by spaced plates, said plates forming a double wall. The inner ofthese plates is indicated by 17 and the outer, by 18. Each of theseplates is bent around to form the side and rear walls of the bucket. Thelower edges of these plates 17 and 18 are attached to the flanges 15 and16 of the casting by means of rivets 19. Between the plates 17 and 18are placed spacing members, here shown as I-beams 21 held in position bysuitable rivets. The upper edges of the side walls and rear wall of thebucket are Y formed by cast channel members 22, 22, said members havingan upper rounded edge or web` and depending flanges 22a, 22a lyingbetween the upper edges of the'plates 17 and 18. The members 22 are heldin position by suitable rivets 23. Y

The bottom rear portion of the bucket is protected and strengthened byremovable shoes or wear plates. As here shown, there are three Aof theseplates, two outer plates 24, 24, anda center plate 25. These plates vareprovided with depending hollow ridges 26,

which accommodate ridges 27 cast on the bottom surface of the bottomportion l1 of the bottom cast member 10. The sides of this member areprovided with curved projecting lugs l()a against which the forward endsof the shoes 24 butt. This engagement is afforded by the side portions24a of the outer shoes or plates 24:, 24 which are curved upwardly ashort distance at the sides of the bottom member 10.

The ridges or ribs 27 on the bottom member 10 are provided withcross-ridges 27a engaging suitable sockets in the shoes or wear plates2a and 25 to assist in preventing longitudinal movement of the same onthe bottom of the bucket. The shoes 24 and 25 are held in place bysuitable rivets, indicated by 28, 28.

The forward edges of the side Walls of the bucket are closed by suitablecastings 29 carrying hinged members 30 to which the loading line (notshown) is attached, eyes 80a being provided for such attachment. Numeral31 may indicate trunnions for supporting the bucket, 82, the supportingchains and 83, the holding line, which assists in preventing the bucketfrom dumping when supported by the chains 32, all in accordance with theusual construction and operation of the Page bucket.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invention as broadly as permissible, in View of the priorart.

lVhat I regard as new, and desire to secure by Letters Patent, is; y

l. A bucket of the character described, including; a cast bottom member,said member having separated flanges at the side and rear; spaced platesattached to said flanges to form the side walis and rear Wall of thebucket; and a closure member attached to the upper edges of said platesextending along the sides and across the rear of the bucket.

2. A bucket as claimed in claim 1, in which the spaced plates are heldin spaced position and strengthened by spacing members ar- 5 rangedbetween the same.

3. A bucket as claimed in claim 1, inl which the cast bottom member isprovided with longitudinal ribs, in combination with removable shoes orwear plates adapted for at tachment to the bottom rear portion of thecast bottom member, said shoes or wear plates being provided withgrooves adapted to ac- ,cgommodate the ridgeson the bottom mem- 4;. Abucket as claimed in claim 1, in which the bottom cast member hasprojections on the sides and in which there is provided removable shoesor Wear plates adapted to be attached to the bottom rear portion of the,

cast bottom member, said shoes or Wear'l plates having portionsextending upwardly
